Dear Larry,

Thank you for your mail. But concerning to "capa flags index 3", I am not sure. Please look
following message receiving for command "ps aux",

I am not software expert, but also looking on message from abrt:

Subject: [abrt] : divide error: 0000 [#1] SMP => look attachment.

Maybe it is direct consequence connected with my wi-fi problem...

Hello,

Allow me to ask you the following question:

I have laptop with: "02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)".
For this device I found firmware iwlwifi-7265-ucode-25.30.14.0.tgz.

My problem is following: This firmware was created for kernel 4.2+, but I am using Centos 7 with kernels a la 3.10. Therefore I see during booting and after switch off some
problematic messages a la:
capa flags index 3 larger than supported by driver  or
failed to remove key (2, ff:ff:ff:ff:ff:ff) from hardware ...

Wi-fi works properly, not to look on the previous messages.

My question to you: do you have in schedule to include proper firmware also for
centos 7/redhat 7?

If your kernel were newer, I would recommend running the backports drivers, but I think 3.10 is too old. That said, this code change would not fix the "failed to remove key" message as I get that on my 7260 device with kernel 4.16.0. I think you may safely ignore this one if for no other reason than it only happens when the device is being shut down.

If the "capa flags index 3" message is not causing any problems, I would ignore it as well.

On this and most mailing lists, one should not top post. It is most inconvenient to have to continually scroll up and down to get to your comments while writing mine.

In your first posting, you said "Wi-fi works properly". That certainly does not imply any problems other than the strange messages in the log. If you are getting BUG and/or WARNING dumps, then the output of the dmesg command will list the traceback. I do not see any of those. They may be a consequence of using such an old kernel. I am only an Intel wifi user, not a developer, and it is unlikely that I will be able to fix any of your problems. In any case, you need to post the full tracebacks of those BUGS/WARNINGS here. Remember, do not post at the top.

Larry

A: Because it puts things out of order.
Q: Why is top posting bad?
